This is to define the API sstable needs from underlying storage. When implementing object-storage backend it will need to implement those. The API looks like
future<> snapshot(const sstable& sst, sstring dir, absolute_path abs) const;
future<> quarantine(const sstable& sst, delayed_commit_changes* delay);
future<> move(const sstable& sst, sstring new_dir, generation_type generation, delayed_commit_changes* delay);
void open(sstable& sst, const io_priority_class& pc); // runs in async context
future<> wipe(const sstable& sst) noexcept;
future<file> open_component(const sstable& sst, component_type type, open_flags flags, file_open_options options, bool check_integrity);
It doesn't have "list" or alike, because it's not a method of an individual sstable, but rather the one from sstables_manager. It will come as separate PR.
